Abstract
An organic electroluminescent display substrate including: a substrate; a display region; a transitional region; a packing film that extends from the display region to the transitional region; and a through hole. The display region includes an insulating layer on the substrate with an organic electroluminescent component thereon. The transitional region includes: a recessed portion and a redundant layer on the substrate and in the recessed portion. An opening size of one side of at least one part of the recessed portion away from the substrate is not greater than an opening size of another side of the at least one part of the recessed portion adjacent the substrate. The packing film covers the organic electroluminescent component and at least one part of the recessed portion. The through hole extends through the packing film, the redundant layer and the substrate in a region where the recessed portion is located.
